Description

Modification method and modification system for barrier-free micro-disturbing elevator installation of existing house

Technical Field

The invention relates to the technical field of existing residence-mounted elevators, in particular to a modification method and a modification system of an existing residence barrier-free micro-disturbing-mounted elevator.

Background

At present, china is in a stage of fast aging, a large number of existing houses have no elevator, and the existing houses are extremely unfriendly to the living of the old, so that the existing houses are additionally provided with the elevator, and the existing houses become urgent demands.

At present, the technical scheme of installing an elevator in an existing house mainly comprises the following steps:

(1) An elevator is additionally arranged at the outer side of a residential stairwell, and a stopping platform is arranged at a stairwell resting platform. The scheme does not change the original stair structure, and has simple technology. However, most of the stairs of the existing house are double-running concrete stairs and are difficult to replace, and a stopping platform of an elevator is arranged at a half-layer rest platform, so that a resident can only stop at a half-layer, and the resident must go on the upper half-layer or the lower half-layer before entering and exiting, so that the difficulty of climbing stairs is reduced, but the barrier-free requirement is not met, and particularly, huge difficulty still exists for old people or disabled people;

(2) An elevator is additionally arranged on the outer side of the outer wall of the house, a landing platform is arranged at the elevation of the floor entrance, and the landing entrance is realized through additionally arranging a corridor component or a balcony and a door opening formed in an outer window. The technical scheme is simple and easy to realize, but the position of the entrance door is changed to the outer wall, and the entrance line must pass through the kitchen and bedroom of the residence, so that the original functions of the residence indoor room are destroyed. Because old community small households are more, the number of elevators to be added is more, the cost is higher, and balcony and vestibule components can also have adverse effects on lighting and privacy of the house;

(3) An elevator is additionally arranged on the outer side of a residential stairwell, a stopping platform is arranged at the same height as a floor, and the original stairwell is modified to realize flat-layer entrance. The main technology comprises the following steps: the method comprises the steps of cutting off one section of the original double-track stair and half of the rest platform, additionally arranging a connecting stair section between the platform and the original stair rest platform, changing the original stair from double-track stair to single-track stair, and additionally arranging a horizontal floor between the elevator stop platform and the entrance floor. Many related technologies exist in the scheme, such as a support is added between the double-ladder running, and the method has a certain help in improving the feasibility of the technology. However, there are a number of problems with this type of technology, such as the structure of the landing platform is connected to the walls on both sides, and the structure of the landing platform cannot be supported after removal, and if the support is added, the landing is occupied in the stairwell, resulting in insufficient traffic width, and no feasibility. In addition, the method for installing the elevator does not consider the limiting conditions in the construction process. In general, the construction period of the elevator is not less than 2 months, if the original stairs are cut, residents cannot travel, or the residents can leave for 2 months, so that the method is not feasible.
